SEWER-INLET OR BASIN COVER.

SPECIFICATION forming part'of Letters Patent N 0. 718,277, dated January 13, 1903.

Application filed December 27, 1901. $erial No. 87,471. (No model.)

To all whom it may concern:

Be it known that 1, MICHAEL W. PETERS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Sewer-Inlet or Basin Covers; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it-pertain s to make and use the same.

My invention relates to sewer-inlets, and more especially to that class known as catchbasin covers, and adapted to be located outside of the curb-line and act as a cover for the catch-basin.

The object of my invention is to provide the aforesaid inlet with an adjustable curbbox adapted to be adjusted at any predetermined angle in relation to the grate-frame, and hence allowing the curb-box to aline itself or be alined with the curb, regardless of the grade of the pavement or the curvature of the same in cross-section, thus allowingthe cover to be set in alinement with the grade and curvature of the pavement and curb-box to be adjusted to proper adjustment to aline itself with the curb.

Another object of my invention is to form the curb-box with a diverging or slanting back, so as to direct the drain or sewage to the catch-basin without checking the same or permitting the sewer to become closed.

My invention consists in the peculiar features of construction whereby the above re sults are attained in an economical and practical manner and whereby the parts after having been once adjusted are held positively in position without danger of sinking or becoming out of alinement through corrosion of the fastening, all of which will be hereinafter fully set forth and claimed. 7

In the drawings, Figure I is a view in isometric of a basin cover or inlet embodying my invention. Fig. II is a section view taken on the line was, Fig. I, illustrating the angle of the rear wall of the inlet and also the method of securing said rear wall in adjustment.

A represents the grate frame or casing, which may be of any suitable construction or shape adapted toform a base or seat for the grate. This frame or casing A forms a coverin connection with the grate of .a basin located outside the curb-line and is adapted to be so placed upon the upper course of the basin that its upper surface a shall be flush and even with the upper surface of the pavement or that the upper surface of the grate shall conform both in grade and curvature with the pavement.

To the rear of the frame or casing A is a curb-box B, having an open front or inlet which extends above the upper face of said frame A for the purpose of receiving that portion of the drainage which does not pass through the grate. This curb-box B is of such height and thickness or depth as to conform with the curbing of the street and is provided at its rear with an inclined backwardly and downwardly projecting wall B, which corresponds, preferably, with the inclination of the back end of the frame A. (See Fig. II.) This rear wall B of the curb-box B is formed so as to rest upon the upper end of the rear portion of the frame A, but may also be adjusted to assume an inclined position in relation thereto by providing the rear end of the frame A with a flange A, adapted to engage the inner face of the rear wall 3' of the box B, leaving thus a shoulder or ledge a at the upper portion of the frame A at its back end and breaking the joints between said back end of the frame A and the rear wall of the box B. This flange A also affords a means for seen ring the back portion of the box B adjustable in relation to said frame A, and for this purpose aslot a is provided in either the back B or the flange A,

or in both, and a bolt, preferably of non-oxi-- dizable material, is employed, as at b, for securing the parts in adjustment.

I form the lower ends of the sides of the box B with a curved seating portion O, which rests upon the edge of the frame A, as at c said frame being preferably cut away so as to form a seat beneath the upper edge of the frame A, and thus allow the box B at its lower edge to rest beneath the plane of the frame proper.

The forming of the sides with curved seating portions 0, which rest upon the upper edge ofthe frame A, is for the purpose of first positively supporting in a vertical direction the said box B upon the said frame A,

Too

while at the same time allowing said box to be adjusted or tilted to assume an inclined position within certain limits at any angle to the frame A. As a further support for the box B, I provide the same at the inner face of the said walls with downwardly-extending lugs D, which are pivotally secured by means of non-oxidizable bolts 61 d to said frame A. The lower ends of the lugs D rest in seats formed in the upper ends of projections D, which are integral with the frame A, and it will thus be seen that while the pivotal attachment d and curvature 0 allows of the angular adjustment of the box B the said box is nevertheless supported positively at all times regardless of said angular adjustment, and that even should the rivets or bolts (Z become corroded or broken the said box would be held in position by means of the lugs D, blocks D, and curved seat 0.

The angular adjustment of the box 13 is attained by loosening the nuts on the bolts 1) and (l d, which will permit the said box to be rocked or tilted on its pivotal bolts 6? d to the desired inclination, and after which by tightening the nuts on the said bolts the curbbox is held rigidly in relation to the frame in its adjusted position.

In setting forth my invention I have illustrated certain details and assemblages which may he changed without departing from my invention.

What I claim is- 1. In a sewer-inlet or basin cover of the type set forth the combination with the grateframe, of a curb-box open at its front end, said curb-box having curved lower edges, at its sides adapted to engage and rest upon the upper edge of the grate-frame, and being pivoted to said grate-frame in such a manner that said curb-box may be inclined forward or backward in relation to said frame for the purpose set forth.

2. In a sewer-inlet or basin cover of the type set forth the combination with the grateframe provided with a flange A of a curbbox adapted to engage said flange with means for securing the rear wall of said curb-box adjustably to said flange; and curved lower edges at the sides of said on rb-box adapted to rest upon the edge of said frame with means for pivotally attaching the curb-box to said frame, the whole providing means whereby the curb-box may be adjusted at different angles to the grate-frame.

3. In a sewer-in1et or basin cover of the type set forth the combination with the grateframe having an outwardly and downwardly inclined rear side or end, with a shoulder and flange at its upper edge, of a pivoted curb-box, pivotally secured to said grateframe by means of inwardly and downwardly projecting lugs, said curb-box having an inclined back wall, inclining outwardly and downwardly and coinciding with the inclined face of the grate-frame, with means for adjust-ably attaching said inclined wall of the curb-box, to the grate-frame, substantially as and for the purpose set forth.

Signed at Cleveland, county of Cuyahoga, and State of Ohio, this 24th day of October, 1901.

MICHAEL W. PETERS.
